Answer 1

Answer:

R = looxl/PxN

= 100x250/ 6000x2.5=1.67%

Answer 2

The required rate of interest is 1.67 % per annum.

Given:

SI = Rs 250

P = Rs 6000

T = 2.5 years

To find: Required rate percent per annum

Solution:

According to the question,

Simple interest SI = Rs 250

Principal P = Rs 6000

Time T = 2.5 years

Let required rate of interest per annum = R

According to the formula for simple interest we have

SI = (PxRxT)/100

⇒ 250 = (6000 x R x 2.5)/100

⇒ 60 x 2.5 x R = 250

⇒ 150R = 250

⇒ R = 250/150

⇒ R = 1.67

∴ The required rate of interest is 1.67 percent per annum.
